NAME
       hesiod_getmailhost,   hesiod_free_postoffice  -  Hesiod  functions  for
       retrieving user to postoffice mappings

SYNOPSIS
       #include <hesiod.h>

       struct hesiod_postoffice *hesiod_getmailhost(void *context,
            const char *user)
       void hesiod_free_postoffice(void *context,
            struct hesiod_postoffice *po)

       cc file.c -lhesiod

DESCRIPTION
       This family of functions allows you to retrieve user to postoffice map-
       pings using Hesiod.  To perform lookups, you need an initialized Hesiod
       context; see hesiod(3) for details.  Information is returned in a  hes-
       iod_postoffice structure, which has the following fields:

       hesiod_po_type
              The type of postoffice box, typically ``POP''.

       hesiod_po_host
              The hostname where the postoffice box resides.

       hesiod_po_name
              The account name on the given postoffice server.

       It  is  the caller's responsibility to call hesiod_free_postoffice with
       the returned postoffice entry to free the resources used by the postof-
       fice entry.

       Hesiod  queries for postoffice information are made using the ``pobox''
       Hesiod type, using the username as the Hesiod name.  The  corresponding
       entries  should  be space-separated lists of strings giving the type of
       postoffice box, the hostname, and the account name.

RETURN VALUES
       On failure, hesiod_getservbyname returns NULL and sets the global vari-
       able errno to indicate the error.

ERRORS
       hesiod_getmailhost  may  fail  for  any of the reasons the routine hes-
       iod_resolve may fail.
